Hyaluronic acid is a polysaccharide (carbohydrate) that occurs
naturally in the body. It exists in all mammals, and is identical
in all species and tissues. Higher amounts of HA are found in the
skin, vitreous body and connective tissues in the human body.
Most important property of HA is its water binding capacity that
furthermore gives structure to tissue and lubricates joints and
muscles. HA also acts as a shock absorber in the weight bearing
joints.
Properties of Hyaluronic Acid:
Moisturization properties: Formation of a barrier on the skin and high water binding capacity
Wound healing properties: Normalization of cell migration and proliferation
Mechanical effect: Lubrication, cushioning and shock absorption.
Nutrient effect: Transport of essential nutrients from the bloodstream to living skin cells
Pharmacological effect: Cell signaling (CD44 receptor)
